"myocardial scar tissue (will usually not have any associated myocardial oedema, but differentiation is rather difficult)"
"Myocardial necrosis can be displayed with inversion recovery gradient echo images as a late gadolinium enhancement or in case of microvascular obstruction as void or lack of any enhancement 3,5. The enhancement is due to an increase of extracellular volume as a result of leakage of intracellular components into the extracellular space and hence increased volume of distribution for gadolinium-based contrast agents. It might be subendocardial, transmural, subepicardial or patchy depending on the aetiology 5,6."
